All of Israel are responsible for one another. - Yehuda Ashlag

Anything that is perceived and sensed by the five senses, or which takes time and space, is called 'Corporeal.'

[S]ince the essence of the soul is but a will to bestow, and all its manifestations and possessions are fulfillments of that will to bestow (...) therefore it is immortal and irreplaceable. The soul, with all its manifestations is eternal and exists forever. Absence does not apply to them upon the departure of the body. On the contrary, the absence of the corrupted form of the body, greatly strengthens it, thus enabling it to rise to the Heavens. Thus we have clearly shown that the persistence in no way depends upon the concepts it has acquired, as philosophers claim, but its eternality is in its very essence, meaning in its will to bestow, which is its essence. And the concepts it acquires are its reward, not its essence.

It is well known to researchers of nature that one cannot perform even the slightest movement without motivation, meaning without somehow benefiting oneself. When, for example, one moves one’s hand from the chair to the table it is because one thinks that by putting one’s hand on the table one will thus receive greater pleasure. If one would not think so, one would leave one's hand on the chair for the rest of one's life without moving it an inch, all the more so concerning greater efforts.
